It is known that car a travels 65 kilometers per hour and car B 55 kilometers per hour. How many meters is the distance between the two places?
65 + 55 = 120m 120 × 4 = 480m
A. B is 210 km away from the two places. Car a and car B start from the two places at the same time and run in opposite directions. After two hours, they meet. It is known that car a does not travel 55 km per hour
How many kilometers per hour does car B travel? It's very urgent
A. B is 210 kilometers away from the two places. Car a and car B start from the two places at the same time and run in opposite directions. After two hours, they meet. It is known that car a does not travel 55 kilometers per hour, but how many kilometers per hour does car B travel?
210÷2-55
=105-55
=50 km / h
Party A and Party B travel from two places at the same time. Party A travels 25 kilometers per hour by electric bicycle, and Party B travels 15 kilometers per hour by bicycle. How long is the road when they meet 8 kilometers from the midpoint
Jiaduo walked 8 * 2 = 16 kilometers
Time 16 / (25-15) = 1.6 hours
Distance = (25 + 15) * 1.6 = 64km
Party A and Party B walk from both places at the same time. Party A walks 60 meters per minute and Party B rides a bicycle 190 meters per minute. A few minutes later, they meet 650 meters from the destination
Less conditions, the total distance x should be given (X-650) / (60 + 190) = the result is the answer
